Application Scenarios
-
Petrochemical Hazardous Area Temperature Monitoring: The D5072D converts temperature signals from field thermocouples and RTD sensors installed in explosive petrochemical zones into isolated standard 4–20 mA signals for INFI90 DCS acquisition. Its SIL 2 safety certification meets mandatory safety integrity requirements for flammable process environments, while galvanic isolation blocks field interference and transient voltage damage to core control equipment, ensuring stable and accurate temperature monitoring for reaction vessels and distillation units.
-
Thermal Power Plant Safety Instrumented Systems: In power generation safety loops, this signal converter processes critical boiler and pipeline temperature measurements. Reverse polarity protection and overload resistance prevent signal transmission failures caused by on-site power anomalies. Consistent high-precision conversion eliminates data drift during long-term operation, supporting precise closed-loop temperature regulation and improving the overall safety and stability of power plant thermal control systems.
